Measuring approximately 38 metres north to south and 33 metres east to west, this raised earthwork is defined by a scarp ranging from 1.5 to 2.3 metres in height. The only visible remnant of the original masonry can be found at the southeast corner, though it’s now heavily obscured by a thick covering of ivy.

The site carries significant historical weight in the region’s past. According to P.W. Joyce O’Rorke’s 1890 writings, Longford served as one of the principal seats of the O’Dowd clan, a powerful Gaelic family who held sway over this part of Sligo for centuries. The genealogical manuscripts of Duald MacFirbis, the renowned 17th century Irish historian, provide an intriguing detail about the castle’s construction; he noted that the English built “all the bawn of Longford, except Leaba an eich bhuidhe”, which translates to “the bed of the yellow steed”. This cryptic reference likely points to an earlier Irish fortification or sacred site that predated the English castle.

Today, the platform has been incorporated into the landscape design of Longford House’s grounds, serving as a reminder of the layers of history embedded in the Irish countryside. While the castle itself has vanished, its footprint continues to tell the story of conquest, resistance, and the changing fortunes of Gaelic and English power in medieval and early modern Ireland.
